Client crash with entity network handling

[LemADEC]

As of ICBM-1.7.10-2.15.1b438 & VoltzEngine-1.7.10-1.4.0b94, when adding those on client side and connecting to a dedicated server, client will crash on

If ICBM-Classic is also added, you can get a variant with EntityMissile instead of EntityFragment.

Check to make sure your entity IDs match server side and client side

I can't seem to find the configuration to change ICBM or ICBM-Classic Entity IDs. so I guess it's hardcoded?

[DarkGuardsman]

should be a config but I'll check here later
